I'm very confused. I ordered new rear brake drums from the Autozone.com website for my truck and they just arrived. Problem is, they don't look like the right ones to me. ?
I have a 1971 C20 with what I believe is an Eaton rear. (it has the large salad bowl center and the bolts are on the front side) On the website, they have 2 possibilities, one with a Dana rear and one without. I clicked the one without and ordered them. (see pics below) The ones shown are 11 5/16" X 2 3/4" I haven't had my drums off for a few years (truck is off the road) but when I did have them off last, I had to remove the center hub and pull the axle to get the drums off. The ones below look like that wouldn't need to be done. Questions are; 1) Do I have an Eaton rear as I described above? 2) Are the drums in the pics correct? If not, what are they correct for? Thanks in advance for any help... Bob

Re: 3/4 ton brake drum confusion!
They are correct! You have to remove the hub from the drum. If I remember correctly the wheel studs are what hold them in place.

Re: 3/4 ton brake drum confusion!
Take out the axle. then use a special hub socket. either has 4 or six prongs that will go into the spindle nut. take spindle nut off the a washer, then another spindle nut. The whole heavey SOB should slide of the spindle now..
The just get a brass drift and a heavy hammer and pound out the lugs. You can reuse them if you don't mess them up. Then reverse process and all should be A OK....

Re: 3/4 ton brake drum confusion!
Yeah the wheel studs "pound" out very easily -- but be sure to take it in and have a shop with a press and PRESS on the new assembly together.
Last fall I POUNDED my studs into the drum and hub and let me emphasis the pounding part. The last 1/4" of the studs to get down tight are a bugger. Just take it in for the whole disassembly/reassembly. I wouldn't do it myself again without a press.

Re: 3/4 ton brake drum confusion!
Just a follow up...
Everything went real smooth and just as you guys told me. It was also the perfect time to justify buying a new tool for the garage.... A 12 ton shop press. ![]()
